Billy Joel and model Christie Brinkley prove that you can stay friends following a divorce.

Billy Joel recently serenaded Christie Brinkley during a version of ‘Uptown Girl’ at a show in Madison Square Garden. The singer asked for his camera crew to capture her smiling and dancing in the front row. Brinkley shared her own reaction on Instagram , boasting about her ex husband, "He’s still got it!"

The couple were married and had a daughter together, but divorced in 1994. Joel was on his River of Dreams tour during the divorce and ‘Uptown Girl’ was missing from his set list at the time.
